Something I suddenly thought of

The summer vacation campaign is also nearing its end. While thinking that, I suddenly had a thought yesterday. This image shows items that increase the drop rate for things like large fragments and experience points, but I've already maxed them all out. On top of that, I have this much left over... Honestly, isn't it a waste? Since I end up with a considerable amount left over every year, I find myself wishing we could exchange them for items or something, like the office item tickets. Hey devs, can you please consider making a system like that next year? Am I the only one with this much leftover?
